You can put this solution on YOUR website!
let's let L be length and W be width.
\n" ); document.write( "From the question we know that
\n" ); document.write( "\"L=8%2BW\"\r
\n" ); document.write( "\n" ); document.write( "We also know that the perimeter of a rectangle can be calculated using the formula
\n" ); document.write( "\"P=2L%2B2W\"\r
\n" ); document.write( "\n" ); document.write( "Now substituting the 8+W for L and the given perimeter we get:
\n" ); document.write( "\"24=2%288%2BW%29%2B2W\"
\n" ); document.write( "\"24=16%2B2W%2B2W\"
\n" ); document.write( "\"24-16=4W\"
\n" ); document.write( "\"8=4W\"
\n" ); document.write( "\"8%2F4=W\"
\n" ); document.write( "\"W=2\"\r
\n" ); document.write( "\n" ); document.write( "Well if W=2, we can find the length using the first formula we can up with
\n" ); document.write( "\"L=8%2BW\"
\n" ); document.write( "\"L=8%2B2\"
\n" ); document.write( "\"L=10\"
\n" ); document.write( "
\n" );
